The sum of the two angles in HP notation will be in the X register (line 1) 52. Complex numbers are treated as a single value instead of two separate values. In the case of solving, the program is treated as an expression whose return value (the value left on the stack) should be zero. An equation may be processed in a number of ways. A cross-product function is not available, nor any function to extract individual elements from a vector, but these can be readily calculated by the user. [13], The 35s's lack of communication abilities makes it acceptable for use in some professional examinations where more powerful calculators would not be. With only 26 labels, it was difficult to write programs making use of the entire 30 KB of memory. Each unit is booted from its image unless you specify otherwise with options to this command. The 35s provides facilities for handling vectors of up to three real-number elements. Indirect branching, which allows the contents of a memory register to be used as the target of a branching instruction (GTO or XEQ) is omitted from the HP 35s. ‎On January 4, 1972, Hewlett-Packard announced the HP-35, world's first scientific calculator small enough to fit in a pocket - more precisely, Bill Hewlett's shirt-pocket.
